Water heater trouble shows up in a few common ways: no hot water, hot water that runs out quickly, rumbling or popping from the tank, rust-colored water from the hot tap, or water pooling around the base. Some of these are simple fixes. Others point to a tank that is near the end of its life.
On a tank-style gas heater, a lack of hot water often comes down to the pilot, thermocouple, or gas valve. On an electric model, a heating element or thermostat is a common culprit. Sediment buildup causes the rumbling noise and shortens tank life. A leak from the tank body itself usually means replacement, while a leak from a fitting or the relief valve can often be repaired.
Haygood Plumbing connects you with an independent plumber in Houston, TX who works on water heaters. The plumber who takes your job will look at the age of the unit, the type of failure, and the venting and gas or electrical connections before recommending a repair or a new unit. If replacement is the better choice, ask about tank size, gas versus electric, and whether a tankless model would work in your home.
Before you call, check the label on the side of the tank for the brand, model, and capacity, and note roughly how old the unit is. If the tank is leaking, turn off the cold water valve at the top and shut off the gas or flip the breaker for an electric unit.
Ask whether a permit is needed for a replacement in Houston, TX, since many areas require one, and what the price includes, such as haul-away of the old tank and any code upgrades like a drain pan or expansion tank.
